How much elevation range does the M120 offer when carrier-mounted?

The M120 mortar, when carrier-mounted, provides an elevation range of 750 to 1510 mils. Understanding this range is important as it allows operators to adjust the mortar's angle for accurate targeting over various distances and terrains. The specified limits mean that the mortar can be effectively employed in a wide variety of operational contexts, accommodating different target elevations, from flat terrains up to elevated positions.

The details contained in option A reflect the intended operational capabilities of the M120, emphasizing how it can adjust for fire accurately based on the necessary elevation to match ground conditions and target location. This is essential for maximizing the effectiveness of the mortar in combat scenarios.

The other options present different ranges that do not align with the specifications of the M120 mortar, focusing instead on either incorrect elevation in mils or using distance measurements in meters that do not correlate with its elevation setting. Thus, option A correctly outlines the mortar's elevation capabilities, making it the right choice.
